Deputy head of chemistry, Mr Church, is about to resign from Greybridge School but the arrival of Miss Postern, the new French teacher, changes everything. PE teacher Mr Gunn also has designs on the new member of staff.

The school holds a talent show but this time the teachers perform and the pupils are the judges.

Miss Postern is in charge of the draughts club and suggests merging with Mr Church's chess club, creating the school's first `chaughts' club. She goes to his place to discuss a merger and watch Strictly.

Miss Postern warns the other teachers to be sensitive with troubled pupil Josh when his mother runs off with a Maasai tribesman, and he is given a part in `Romeo and Juliet' put on by the drama department.

Miss Postern has put herself down for an ironman competition, and Mr Gunn offers to help with her training. Meanwhile, Drama teacher Mrs Klebb sets up a new action group to stop violence at school.

Mr Church is happy to be involved with Miss Postern's school trip to France but with no places left, he needs to find a way to get on the bus.
